After a last-lap crash in Race 1 at Misano, Chaz Davies has been declared to have broken his back during the incident. The announcement comes after Davies was taken to the Rimini Hospital for further medical assessment, after he was taken by stretcher off the race track – just three corners away from the finish line.

Doctors in Rimini diagnosed Davies with a closed thoracic trauma, which includes aa fracture of the transverse process of the third lumbar vertebra (L3). Davies also suffers from a contusion of the left thumb.

Good news concerning two-time World Superbike champion Max Biaggi, as the Italian rider has been declared stable, after his supermoto training crash last Friday. Airlifted to the San Camillo Hospital, Biaggi suffered from thoracic trauma and multiple rib fractures.

Thankfully, doctors have ruled out that he suffered any spinal cord injuries, which is welcomed news after several weeks of high-profile incidents with former world champion riders.

Max Biaggi is the latest (ex-) rider to be injured in a training crash. The four-time 250cc champion was riding a supermoto bike at the Saggitario track in Latina, just south of Rome, when he crashed the bike.

Biaggi was transported to a nearby hospital, the Ospedale San Camillo Di Roma, where he is being treated with suspected thoracic and vertebrae damage.

When Valentino Rossi crashed his motocross bike while training last Thursday, he triggered a wave of speculation on just how serious his injuries were.

It was clear that there was reason for concern, as the Italian had been taken straight from the motocross track at Cavallara to the emergency room at Rimini hospital. The fact that he was kept in overnight made it even more worrying.

Initial reports from local newspapers and websites validated such concerns. There were reports that Rossi had fractured one or more ribs, that he had injured his shoulder, even that he had taken a blow to the head, and had picked up a concussion as a result.

That presented the Movistar Yamaha team with a serious problem. One which they have handled with considerable subtlety and expertise, it has to be said. Their first and major priority was to control the narrative around Rossi’s injury, giving the media the information they wanted, while keeping their options open.

Crashing during the superbike practice at the North West 200 on Thursday, John McGuinness was reported to have suffered a broken right leg. But now getting an update on his condition, we can see that his injuries are far worse than was initially thought.

While Honda Racing has withdrawn from the rest of superstock and superbike races at the North West 200, because of concerns regarding a mechanical issue causing the McGuinness’ crash, these injuries also cast significant doubt over John McGuinness competing in this year’s Isle of Man TT.

Andrea Iannone is to miss the MotoGP round at Motegi. The Italian has been advised by his doctors to skip the first of the three Pacific flyaway rounds to allow the vertebra he fractured at Misano to heal.

Iannone picked up the injury on the first day of his home race at Misano. Though the injury is on the forward side of the T3 vertebra, making it less vulnerable to a repeat injury, the fracture has caused him to miss both Misano and Aragon. Motegi will be the third race which Iannone will be forced to miss.

Aleix Espargaro has fractured a vertebra in a training accident. The factory Suzuki rider was out training on an off-road bike, when he landed heavily from a jump, and felt pain in his back.

He was taken to hospital, where an MRI scan revealed a flexion fracture of the vertebra, which will force him to miss the Sepang test planned for next week.

The injury suffered by Espargaro should not see him out of action for long. The Spaniard was discharged from hospital on Friday morning, and will now have to rest for a two to three week period to allow him to recover.

After eight days in the Intensive Care Unit of the hospital, doctors are no longer listing him as being in critical condition. With De Angelis no longer critical, he will be able to fly home to San Marino, where he will receive further treatment in the State Hospital in the tiny mountain microstate.

De Angelis’ condition is stable, though he still faces several threats to his health. The good news is that the intercranial hematoma has not grown, meaning it will probably be naturally absorbed by the body in the coming days. Doctors continue to monitor that situation.

De Angelis remains immobilized due to the spinal injuries he suffered. The fractured vertebrae mean he is being forced to lie still while they start to heal.
